Research by the National Oceanography Centre (NOC) explores a promising new method of forecasting bioluminescence, which may improve the monitoring of movements in the ocean, such as fish shoals and internal waves.

A supernova that signals the death of a massive star sends titanic shock waves rumbling through interstellar space. An ultra-dense neutron star is usually left behind, which is far from dead, as it spews out a blizzard of ...

Scientists at King's have built on research they conducted last year to achieve previously unseen levels of control over the travelling direction of electromagnetic wave in waveguides and proved that the process works equally ...

The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but the fundamentals ...

Usually, light waves do not interact with each other. Coupling of photons with other photons is only possible with the help of special materials and very intense light. Scientists in Vienna have now created the strongest ...

Researchers led by Dr. Sebastian Slama of Tübingen University's Institute of Physics have succeeded in directing the fluorescence of ultracold atoms into surface plasmons – light waves oscillating across a metal surface. ...

Venus is hiding something beneath its brilliant shroud of clouds: a first order mystery about the planet that researchers may be a little closer to solving because of a new re-analysis of twenty-year-old spacecraft data.

Observing the quantum behavior of light is a big part of Alan Migdall's research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons—-the particle complement of light ...

Light

Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400–700 nm, or perhaps 380–750 nm.) In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.

Three primary properties of light are:

Light, which exists in tiny "packets" called photons, exhibits properties of both waves and particles. This property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics.
